AUXILIARY INFANTS SEAT.

To all whom it may concern:

Be it known that I, FRANK H. KNIGHT, a citizen of the United States,residing at Lancaster, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inAuxiliary Infants Seats, of which the following is'a specification.

This invention relates to auxiliary detachable infants seats forwater-closets, commodes and the like, the objects being to provide sucha seat with a folding rest in which the infant may be strapped which maybe folded very compactly for shipping and storage, thus guarding againstbreakage or damage during transit, and to further provide detachablemeans for quickly and securely attaching the same to the usual seat ofany thickness, said objects being accomplished by the construction,combination and arrangement of parts all as hereinafter moreparticularly set forth and claimed.

In the accompanying drawings: Figure 1 represents a'side elevation of adevice embodying my invention as attached to a closet seat, the latterand the bowl being indicated in dotted lines; Fig. 2, a verticallongitudinal central section through the same, the rod and clampingelements being shown in side elevation and the permanent seat B beingindicatedin dotted lines as clamped between seat 3 and the clampingstrap 10 and plate 13; Fig. 3,'a top plan view of the seat,

" rest and clamping elements in their folded position; and Fig. 4, avertical central longitudinal section on line H of Fig-""3.

Referringnow in detail to the "drawings, A indicates the bowl and Bthe'permanent hinged seat, both being of any usual construction asindicated in dotted lines in Fig. 1.

1 indicates the bottom of the auxiliary seat having the usual smallopening 2 and provided with a slot 3 running'longitudinally of bottom ofseat 1 from the center of the rear edge thereof. Front arms 4:,connected at their upper ends to the U-shaped rest 5 by pivots 6 nearconnected by pivots 7 to angle pieces or brackets 8 secured to thebottom or seat 1 by screws 9, said brackets 8 being arranged on a lineat right angles to the longitudinal central line of the bottom or seat 1and near the front of the latter.

- Specification of Letters Patent.

and

the ends thereof, are "5 is first swung Patented July 20, 1915.

Application filed January 16, 1915. I Serial No. 2,545.

To the underface of seat 1, and in line with and 'swingingthrough slot3, is the clamping member or strap 10 pivotally conneoted to a littlebracket, lug'or fitting 11 by a pivot 12, the said lug 11 being fastenedby any suitable means to the underface of said seat 1. This strap 10 isprovided with an Integral clamping plate 13 on its outer end and has alongitudinal its pivot 12 and said plate 13. Also, said strap 10 is madeof resilient metal or other suitable resilient: material and is bentupslot 14: between ward at an angle of about45 degrees at a I pointabout one third of its length away from its pivotal point 12, sothatwhen portion a of said strap 10 lies-fiat against the underface of trudethrough slot 3 with the plate 13 well above the upper surface of seat 1,as shown in Fig. 4, and when the strap 10 is swung down so that theportion a. is at an angle of about 45 degrees to seat 1 the portion I band plate 13 will lie parallel to said seat 1, as shown in Fig. 2.

' A bar or rod 15, fulcrumed on rod 16 mounted in bracket 17 secured tothe upper face of seat 1, is pivotally connected to lug 18 riveted tothe center of the back of rest 5 and has its lower end protrudingthrough slot i l in strap 10, bent forward at a slight angle andscrew-threaded near its-end to receive a winged nut 19 which bearsagainst the under surface of portion a. of the strap 10, see Fig. 2,thus obtaining the full benefit of the resiliency of the strap 10 aswell as the compressing action of the nut 19 in the clamping operation.Bending the end of rod 15' forward deflects it out of the way of theinner edge of the permanent seat B when setup, also it allows the rest 5to fold down flat while using a shorter strap 10 provided with a slot14: than would be the case were the rod-15 perfectly straight, as willbe obvious from the drawings.

A restraining strap 2-0 may be provided to connect the end of rest 5'bysnap hooks, or in any other suitable or usual manner.

. In operation, to attach the seat 1, the rest to its highest position.The auxiliary seat 1 is then slid on the usual permanent seat B with thepart of seat 1 adjacent slot 3 engaging the upperfaoe of seat B and theclamping plate 13 in line therewith and underneath the lower face of theseat B. The nut 19 is then screwed up on seat 1 the portion 1)will-prothe lower face of said the rod, forcing the strap 10 to swingupward on its pivot until the clamping plate 13 is forced tightlyagainst the under face of the seat B, which is then tightly clampedbetween the under face of seat 1 and the upper face of plate 13. Theinfant may then be placed on the seat 1 and fastened in rest 5 by strap20. To detach it suffices to loosen the nut. 19 by giving it a half turnand then withdraw the seat 1.

To fold the rest 5, seat 1 and clamping elements to their most compactform the rest 5 is to be pushed forward and downward until itliesperfectly flat and parallel with seat 1, with its ends and the arms4 projecting in front thereof. In this operation the. rod 15 through nut19 draws the rear end of strap 10 up through slot 3.

All parts above described are to be made of any suitable materials,though wood is preferred by me for the seat 1 with resilient metal forall other parts, especially the clamping member or strap 10.

It is apparent that various changes may be made in the construction,combination and shape of the "arious parts of my invention, of whichonly the preferred form is shown and described herein,,without departingfrom the spirit thereof, and. it is my intention and desire to includeall such in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An auxiliary seat for infants provided with a folding rest mountedthereon and a clamping device adapted to engage detachably the permanenthinged seat of a water-closet below said auxiliary scat, said devicebeing connected with said folding rest and folding simultaneouslytherewith.

2. An auxiliary seat for infants provided with a folding rest, and afolding clamp mamas adapted "to engage the permanent seat of awater-closet and comprising an upwardly bent slotted strap pivotallyconnected to said auxiliary seat and a screw-threaded rod protrudingthrough the slot in said strap 'and'pivotally connected to said rest,and a pivotally connected to the under face of said seat, a clampingplate carried by said strap, a rod pivotally mounted on said seat,pivotally connected to said rest and having its lower end protrudingthrough the slot in said plate, and a nut turning on the end of said rodand engaging said strap.

5. An auxiliary seat for infants, a rest and arms pivotally connectedthereto, in combination with a slotted strap pivotally connected to saidseat, a rod pivotally mounted on said seat, pivotally connected to saidrest and having its lower end protrud ing through the slot in saidplate, and means moving'on the lower end of said rod and longitudinallythereof and engaging said strap to force it upward.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
